1537 represents "Door Number"
The door is located where the real world meets the dream world.
Between ourselves, it is the one that leads to the world of childhood and dream.
Then, we were innocent and dreamed as much as we could...
Everyone experienced the world in existence.
1537 hopes that we can not only remind the people living in the present of the world
of childhood and dream but also be the way that connects us to the world.
